Looks good to me. With the exception of current monitoring all that could be done with Femto/AC1/JT/e24.

As far as what case we are going to use I think we need to wait till boards are finalized so we know their size and also know everything else we plan to fit in the case. As for I/O what do people want? I was thinking for the back: SE/balanced inputs, maybe a loop out for each, SE/balanced preamp outs. Speaker if you think it's up to the task. Now do we want to use something like the e24 for switching power on/off with a nice lighted switch on the front? Matching switches for switching inputs and outputs? Single 4 pin XLR on the front or dual 3s? Or both. Two SE jacks or one? As for the connectors I was thinking Neutrik for the XLRs and Cardas (OEM price) for the RCA and speaker (if we have it). Or if you guys are feeling froggy WBT but they have a minimum order to get the good OEM pricing. Also what about volume pot? Dact? TP Joshua tree if they are available? If TP had the JT and Femto available we could make it with a nice display and have remote control.

I think you might be right. Looks like about $75 for each transformer. Maybe less since we would be buying in bulk. Hmm....OEM purchase me thinks.

If we are going the SMD route it might be worth while to get the paste stencil and have who ever wants the task to do all the SMD parts. As far as I/O what do you think would be good? Also should we look into converting the SE input into balanced? I also have no problem with a single case design as long as we get a good trafo.

I think this was mentioned before but how about a larger output pad?

If you have one of these The σ22 Regulated Power Supply you are covered.

Also don't count out the Dyn BM5A.

I think this would be a good way to go and would not add that much to the final cost. Most expensive parts would be the cannon plugs/jacks.

Fuck me sideways! I didn't know that either:palm: I might like these after all.

Yup.

I would also prefer a single box version. I really think we all need to come to a group consensus on how we want this built. One version only. Trying to plan for 10 different amps to meet the needs of 10 different people won't work out IMHO. If people want to do their own or stray from the group version then they can buy sub components of the planned group version. Just my $.02.

It is. They make it different versions for different metals. No idea if it's better than other lubricants but it worked good for me. Plus it has a nice cinnamon smell. A nice ratchet tap handle with adjustable collet is also pretty handy.

McMaster-Carr FTW.

I should be careful what I type:palm:. But actually when I was building those B22s I bought a couple nice spiral flute taps and some Tap Magic. Worked wonders and the taps are as good as the day I got them.

I think I would rather volunteer to be the guy to drill and tap the heat sinks than deal with Par Metal.

What is the native format?

For the # we would be buying I think there would be a significant price savings buying the parts direct. I concur. If Kevin is willing to share the board files we may be able to import them and save a bit of time making new boards from scratch.

Am I the only one not seeing anything?

Also depending on what people want this thing to do a I/O board with all the back panel connectors PCB mounted could also make production much easier.

My "?" is because I really don't know what/where I will be in the next couple of months. If I don't have to move I should be able to help out a lot. If this comes down before/during/after my move I won't be able to do much. It would probably be a good idea to do a group buy for all the front and rear panels. Bulk discount plus it will make case work a bit easier.

Looks like for an order with over four units the price is $85 for the 2U 300mm and $100 for the 3U 300mm. For some reason shipping costs are not shown when I add more than three to the cart. If shipping isn't free I would say add about $50 to the price. That's with current exchange rates.

luvdunhill - 8 - 4 Asr - 0 - 4 Stretch - 0 - 4 looser101 - 4 -2 PFKMan23 - 0 - 4 Naamanf -? - 4 As for the cases I think the Hi-Fi 2000 Pesante Dissipante is a good option. And it seems if you order 4 or more they don't charge shipping. Could also be an error in their software.

I would take In 'n Out over the Superbowl.

Tried it. I suggest against getting the Pico for the K240s. It barely has enough power to drive them and forget about listening to them loud. I think they are much more suited to a desktop amp.
